\E. CHAPMAN STUB AXLE FULLER Filed May 2. 1930 Inventor A Itomey Patented July 14, 1931 UNITED STATES EDWARD L. CHAPMAN, F TULSA, OKLAHOMA STUB AXLE FULLER Application filed May 2, 1930. Serial No. 449,266.

This invention relates to new and useful improvements in stub axle pullers, and more particularly to a novel tool which has as its principal object the provision offmeans for sufficient and efficiently pulling axles of the stub type. i

In the following specification and claims, the reader will recognize numerous other important objects and advantages.

In the drawings I Figure 1 represents a longitudinal sectional view through the novel tool.

Fig. 2 represents a fragmentary side elevational view at the door end of the tool.

15 Fig. 3 represents'an end elevation of the tool at the jaw end thereof.

Fig. 1 is a perspective view of one of the link members.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the novel axle puller comprises an elongated cylindrical barrel 5, internally threaded at one end to receive the externally threaded plug 6 through which the crank handle 7 extends.

The portion of the crank handle 7 within the barrel 5 is provided with threads 8 for engagement with the threaded internal head 9 of the connecting rod 10. The opposite ends of the barrel 5 is open and has its edge portion flared outwardly as at 11.

The opposite end of the rod 10 protrudes through the open end of the barrel as shown in Fig. 1. A pair of jaws 1212 are pro vided, each being curved at one end as at 18, so as to converge in the manner shown. A pin 1& extends through each curved end portion of the jaws for pivotally connecting these to the barrel 5. v

The inner side of the outer end portion of each jaw 12 is provided wi-Lh corrugations 15 suitably sharpened to bite into the stub axle to be pulled. Each jaw 12 is provided with an opening 16 therethrough and this opening is suitably pocketed to receive the T-head 17 of a link member 18. The ends of each link member 18 opposite from its T-head 17 is offset as at 19 and provided with an opening 20.

The apertured ofi'set end of the link members 18 are connected together with the outer end of the rod 10 by a cotter pin 21. as shown in Fig. 3.

Obviously, by rotating the crank handle 7, the jaws 1212 may be either contracted or expanded, to clamp against or become re leased from a stub axle.

Obviously, certain minor changes in the shape, size and materials may be resorted to in the manufacture of this novel device withso out departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is H 1. A tool of the character described comprising a barrel, a rotatable crank at one end of the barrel, said crankbeing provided with a threaded extension, a rod slidable through one end of the barrel, an internally threaded head at one end of the rod, said head being adapted to receive the threaded extension of the crank, and a pair of pivotally mounted jaws on the barrel to which the said rod is connected.

2. A tool of the character described comprising a barrel, pivotally mounted jaws at one end of the barrel, a rod slidable through the-adjacent end of the barrel, means at the inner end of the rod whereby the rod may be projected or retracted, and a link member between each of the said aws and the same end of the rod.

3. A tool of the character described comprising a barrel, pivotally mounted jaws at one end of the barrel, a rod slidable through the adjacent endof the barrel, means at the inner end of the rod whereby the rod maybe projected or retracted, a link member between each of the said jaws and the same end of the rod, each of said link members comprising a T-head whereby it loosely connects to the corresponding jaw.

In testimony whereof I afiix my signature.
